From what I understand, sundried tomatoes are inherently easier to preserve than fresh herbs in oil because of the high acidity- I was scouring the internet for pesto canning instructions and came up with a big zero, lol! However this brings up another thing to think about. The skin has its own pH that needs to be maintained for skin health, so I will check and adjust this in my salve. According to a German skin care company's website (sebamed) that is 5.5.
Well with any food grade oil it will have a slightly off odor if it is spent so you could do a smell comparison with some of the same oil used from a fresh bottle. GL
